In these cases of the TI parts, some of their most important specifications, like maximum supply voltage, noise and slew rate, have been changed, and not by a few percent, but by even a factor close to 2.
For so great changes, it is really not acceptable to use the same part number, especially when the part numbers have been in widespread use for many decades, so most users who are familiar to them will not bother to check again their latest specifications, where they could notice that they are no longer what they knew.
